Council-Regular Meeting — October 20, 2026
Marana is tightening rules on data centers after community pushback — new low-frequency noise limits and requirements that companies post financial guarantees to remove equipment and clean up sites when facilities close. One council member worries the town still can't force big operators to comply.
Council-Regular Meeting — October 6, 2026
Two speakers urged the town to take more time on its data center ordinance revisions, saying the current proposal lacks analysis of noise, vibration, nighttime lighting, and impacts on wildlife, livestock, and dark skies — with preliminary estimates of roughly 50 million lumens of light output per night for a large campus.
Planning Commission — September 30, 2026
Marana is tightening the rules for data centers after residents pushed back on noise and cleanup risks. The new rules add low-frequency noise caps, a 5-decibel penalty for tonal noise, 24-hour ambient noise baselines, and require developers to post financial guarantees for decommissioning before construction. Six residents said the rules still don't go far enough — some wanted a moratorium.
